Definitions

• the invention relates to an electromotive handgrass shear with a housing that supports the cutting knives, the drive motor with gear and the batteries and forms the handle that has the actuating switching elements in the vicinity of the handle.
• Handgrass scissors in which a protective housing largely covers the knife and knife drive, such a swivel arrangement is not readily possible.
• the cutting plane of such a motor could be
• driven hand grass shears can be set if they are on a [embosser, in particular on a
• Handgrass scissors such as those used in DE-OS
• the invention is therefore based on the object of an electric motor-operated hand grass shear
• Characteristic part of claim 1 specified features.
• Housing protection function allows adjustment of the knife level without the handle having to be rotated unfavorably with the detected and permanently held switch or the hand being exposed to a risk of injury.
• the cutting head takes up a relatively small space and can also be easily attached with the scissor blades
• Handle and cutting head is provided, through which the cutting head can be relatively laterally offset relative to the handle in any angular position.

• the hand grass shears consist of a handle (10) and a cutting head (12) which is pivotally connected to the handle via an intermediate piece (14).
• the handle (10) has a stem (16) for optional insertion of a guide handle (18).
• the conveniently rechargeable batteries (20) are located in a hollow body in the lower part of the handle.
• a switch button (22) to be operated with the index finger is conveniently mounted, which is held in the off position (FIGS. 1 and 3) by the locking arm (26) of a slide lock (24). It is transferred to the

• Handle housing can be housed, like the similar part (14b).
• the fuse can only be operated with the second hand, which results in increased security.
• Designed handle has a hole or a guide bush in the upper part, in which a pivot pin (34) is pivotably formed, which is integrally formed on the intermediate piece (14) and protrudes from the latter to the rear.
• the intermediate piece (14) has a triangular shape similar to the housing shape.
• Intermediate piece (14) also has a forward projecting in the lower part in the middle section
